    摘要:

    通过对埃塞俄比亚地层、构造、岩浆岩及矿产分布与特征的研究,初步认为:①埃塞俄比亚的地质研究程度普遍偏低,尤其基础地质及其成矿作用和成矿规律方面急需开展重点研究。②地层单元可划分为3类,分别为前寒武纪基底岩系、晚古生代—中生代沉积岩系和第三纪—第四纪火山岩沉积岩系,大地构造位于“泛非构造带”中的东非造山带,多期次构造岩浆活动强烈。③前寒武纪变质岩区主要矿产为金、铂、稀有金属、镍、铜、铁、铬、高岭土、长石、黏土、石棉、滑石、大理岩、花岗岩等;中生代沉积岩区主要有石灰岩、砂岩、石膏、黏土、油气资源等;新生代火山岩沉积岩区主要有褐煤、蛋白石、油页岩、红土型铁矿、斑脱土、黏土矿、珍珠岩、硅藻土、钾盐、石盐、油气及地热资源等。

    Abstract:

    Through study on strata, structure, magmatic rocks and distribution and characteristics of mineral resources in Ethiopia, it is regarded that: ① the degree of geological research in Ethiopia is generally low, especially basic geology, mineralization and mineralization rule are urgently needed to be studied. ② stratigraphic units can be divided into three categories, namely the Precambrian basement rocks, late Paleozoic-Mesozoic sedimentary rocks and Tertiary-Quaternary volcanic sedimentary rocks. Tectonic structures locate in the eastern African orogenic belt in the "universal Africa tectonic belt" with strong multi-stage magmatic activities. ③Major mineral resources occurred in Precambrian metamorphic rock areas are gold, platinum, rare metals, nickel, copper, iron, chromium, kaolin, feldspar, clay, asbestos, talc, marble, granite, etc., while mineral resources in Mesozoic sedimentary areas are limestone, sandstone, gypsum, clay, oil and gas resources. Mineral resources in Cenozoic volcanic rocks area are lignite, opal, oil shale, laterite iron ore, bentonite, clay mineral, perlite, diatomite, potash, stone salt, oil and gas and geothermal resources.
